Ideally, yes
So then,
VeeSA says: "Hur durr, maybes needs encryptions? Much dollars needed!"
And, yet, that is what the SHA hashcube DOES: Encryption.
The blockchain of some good and true coin (not debauched by diff forks) if it can deliver true security where Visa hath fumbled (all their 1000s customers robbed the last holiday) will see an adoption like none every before. AND YET, that coin must think ahead as to how to provide TX identifiers that are true, but which do not contain payload that contains user data.
From a legal perspective, if you look at the crushing penalties for fumbling customer data, well, it makes one want to become a lawyer (haha not really) because of the sheer volume of litigation which is pending against companies that now owe the states millions of theorized-legal-dollars in future terms, because of recent data fumblings.
All acceptors of any customer identifiable data, shall suffer hard fines if they screw that fiduciary duty up. That is what the code says. So, the coin which brings POS security, will exploit the current milieu which is one of customer pain and theft-sufferings.
You would have been good to have in our meeting a few weeks ago when we were discussing a lot of this. That's when we decided to trademark Paysha and register the DBA individually with FinCen
Transaction details only show the address it's coming from and going to. That's like writing a check, as that also has your account information on it. It goes back to what I was saying earlier, though, about the lockbox working one way. Even with your routing and account information, they can only put money in, not take it out.
All information, transactions and payments are verified with multiple layers in our system through several random identifiers, which I won't get into in public for obvious reasons
POS speed like it is with cards won't be possible operating this way, at least not with the current list of coins. There are a few options to do it, but that involves holding funds, which is not something we are looking to do right now. After the recent MtGox bullshit, we want to get the money to the seller as quickly as possible with no delays and not even give an opportunity for us to "misplace" it due to full automation
Another advantage to longer block times is more secure block chains, which is what Paysha is focused on, rather than transaction speed. As said earlier, most merchants are used to 2-3 days for ACH to transfer, so even at a few hours, we are still improving the wait time, not to mention lowering their merchant and transaction fees by +/- 50% depending on volume of credit and debit sales
On a legal note, we are only keeping the minimum amount of required information to keep both our website and payment structure in compliance, and again, that is only for our cold stored records, not to sell or share with anyone else, nor be stored online and accessible to attacks
